What Sets the FLUX 3 Video Generator Apart
Built by Black Forest Labs, the FLUX 3 Video Generator is one multimodal foundation model trained on footage, stills, and sound at the same time. Launched in July 2026, it renders 20-second audiovisual clips, catches subtle facial expression, and scores higher than rival video models in preference tests — all through the Self-Flow training method.
- Cross-Modal Training From the StartBecause footage, stills, and audio are learned together, the FLUX 3 Video Generator grasps how movement, appearance, and sound relate in the physical world.
- Audio Included, Not Bolted OnEvery render from the FLUX 3 Video Generator ships with its own soundtrack — effects, spoken lines, and room tone arrive already aligned to the picture.
- Chained Shots With Consistent CharactersFeed reference frames back in and the FLUX 3 Video Generator links separate clips into longer stories while keeping the same faces and wardrobe across scenes.
Running the FLUX 3 Video Generator, Step by Step
Five input modes, one result: picture and sound produced together by the FLUX 3 Video Generator.
What the FLUX 3 Video Generator Can Do
A single model covering text-to-video, image-to-video, video-to-video, keyframe transitions, and chained multi-shot work — the FLUX 3 Video Generator already outranks leading rivals in early preference testing while development continues.
Five Creative Modes
Start from words, continue an image, restyle existing footage, bridge two keyframes, or extend a clip with sound — five paths through the FLUX 3 Video Generator.
Faces That Read as Real
Subtle expression, multilingual delivery, and emotional nuance come through cleanly, giving the FLUX 3 Video Generator an edge over rival models in early benchmarks.
Self-Flow Under the Hood
Black Forest Labs' Self-Flow method lets the FLUX 3 Video Generator unite generation and understanding of multiple media types inside one underlying network.
Strong Head-to-Head Results
In early comparisons, the FLUX 3 Video Generator was favored over Grok Imagine Video 69% of the time, Runway Gen-4.5 77%, and Luma Ray 3.2 93% — and it is still improving.
Multilingual Dialogue and Typography
Accurate speech across languages and crisp on-screen text come standard, letting the FLUX 3 Video Generator move between camcorder realism and animation.
Open-Weight Release on the Roadmap
Black Forest Labs intends to publish FLUX 3 Dev, an open-weight multimodal backbone, alongside API access to the FLUX 3 Video Generator.
Questions About the FLUX 3 Video Generator
Answers to what people ask most about the FLUX 3 Video Generator and the multimodal video model from Black Forest Labs.
What exactly is the FLUX 3 Video Generator?
It is a multimodal foundation model from Black Forest Labs that learns from footage, stills, and sound simultaneously. The FLUX 3 Video Generator outputs 20-second audiovisual clips with native audio, expressive human faces, and five creative generation modes.
How does it differ from other video models?
Most video models train on pictures alone. The FLUX 3 Video Generator learns cross-modal rules instead — impact lands with matching sound, motion follows physics, faces stay consistent — because every modality is trained at once through the Self-Flow approach.
Which generation modes are supported?
The FLUX 3 Video Generator handles text-to-video, image-to-video (continuation or reference), video-to-video restyling, keyframe-to-video transitions, and generative audio-video continuation from an input clip.
Does it produce audio as well?
Yes. Each output from the FLUX 3 Video Generator carries its own synchronized soundtrack — sound effects, dialogue, and ambience included. There is no separate audio step and no manual syncing.
How long can a clip be?
A single pass through the FLUX 3 Video Generator yields up to 20 seconds. By chaining reference-based generations, you can build multi-minute sequences that keep characters consistent.
Is FLUX 3 open source?
Black Forest Labs plans to ship FLUX 3 Dev as an open-weight multimodal backbone. For now, the FLUX 3 Video Generator is reachable through early-access API and private weight access on bfl.ai.
